The present disclosure provides a method and system of key sharing, the method includes: transmitting, by a group member, a key information request to a neighbor group member; transmitting, by the neighbor group member, the requested key information to the group member, upon receiving the key information request. The system includes: a requester group member and a responder group member. With the method and system of the disclosure, it may improve the reliability and availability of group key and/or auxiliary key distribution, which avoids the bottleneck in service performance and network bandwidth that may occur when all the group members obtain the key from the key server.
